2. TROUBLESHOOTING PROCEDURES
2.5.6.(6) Significant color misregistration
(6-1) Color misregistration occurs.
Check item Check work
Actions to be taken
at NG
(6-1-1) Result of color registration error correction
Color registration
error correction
time (If a printer is
normal, it is approx.
40 seconds.)
Use the self-diagnostic mode and execute the
REG ADJUST TEST. Check the result. Error
is issued but is not displayed on the ON LINE
display.
Replace the
sensor that
causes the
error. Clean
the sensor
to remove
stain. Replace
the shutter.
Replace the
CU/PU board.
(6-1-2) Toner
Remaining amount
of toner
Check if the message “Prepare toner
replacement.” or “Replace the toner.” appears
or not
Replace toner
cartridge with
new one.
(6-1-3) Color registration error detection sensor
Sensor is dirty Is toner or paper dust attached to the sensor? Clean the
sensor to
remove stain
(6-1-4) Color registration error detection sensor shutter
Shutter operation is
faulty
Check the shutter operation by the self-
diagnostic mode
Replace the
shutter or tune
the mechanism
(6-2) Thought REG ADJUST TEST of engine maintenance function results ok, color
misregistration occurs.
Check item Check work
Actions to be taken
at NG
(6-2-1) Paper feed system
Paper feed system
of the paper
running path
Check if any obstacle exists in the paper
feeding path, that hampers smooth paper run.
Remove the
obstacle
2.5.6.(7) Solid black printing.
(7-1) Solid black printing over the whole page
Check item Check work
Actions to be taken
at NG
(7-1-1) High voltage contacting condition
CH terminal Check that the terminal coming from the
printer body contacts with the high voltage
terminal that is located on the left side of the
ID unit when viewed from the top by visual
inspection.
Replace the
terminal of
printer side.
CH terminal Check that the high voltage terminal keeps
the normal contacting condition on the high
voltage board. Open the left cover and remove
the high voltage board. Then, check that
the terminal is not installed in the abnormal
installation condition.
Correct the
installation
condition of
the terminal
to the normal
condition.
ID unit terminal Check that the high voltage terminal of the ID
unit is contacting with the Contact Assembly
normally by visual inspection. (Refer to Figure
2-2.)
Replace the ID
unit or replace
the high voltage
board or correct
the high voltage
terminal.
If any attempt
of using new
ID unit as a
trial is going
to be made,
be sure to use
the System
Maintenance
Menu FUSE
KEEP MODE.
(7-1-2) High voltage output condition
CH output If high voltage probe is available as a
maintenance tool, open the left cover, and
check the CH output with the high voltage
probe from the soldering side of the high
voltage board. (The high voltage probe is not
an ordinary maintenance tool.)
Replace the
high voltage
board.
